The body frame (10) includes a main frame (16) extending rearward from a head pipe (15), a seat frame (19) extending rearward from the main frame (16), and a rear frame (20) extending rearward from the main frame (16) and connected to the seat frame (19). The cable (53) is routed so as to run along the body frame (10). A concave portion (64) depressed in a vehicle width direction is disposed in a connecting portion (55). The connecting portion (55) connects the main frame (16) with a front end portion (20a) of the rear frame (20). A plate-shaped member (65) that covers the concave portion (64) is disposed. The cable (53) is routed between the concave portion (64) and the plate-shaped member (65).

Additionally, in the above-described configuration, the concave portion (64) may be disposed in a side surface (55a) inside in the vehicle width direction.

Additionally, in the above-described configuration, the concave portion (64) may open to an upper side and a lower side.

Furthermore, in the above-described configuration, a side kickstand detecting unit (52) configured to detect a side kickstand (50) may be disposed below the concave portion (64). The cable (53) may be a cable connected to the side kickstand detecting unit (52). An endless driving force transmitting member (39) that extends below the concave portion (64) rearward from the main frame (16) side and is connected to a rear wheel (3) may be disposed. A clamp member (62, 63) that supports the cable (53) may be disposed in a region surrounded by the driving force transmitting member (39) as viewed in a side view of the vehicle.

Additionally, in the above-described configuration, the plate-shaped member (65) may include a step portion (73) that bulges in a direction opposite from a depth direction of the concave portion (64). The cable (53) may be routed between the step portion (73) and the concave portion (64).

The concave portion (64) may be disposed in a front portion (55c) of the connecting portion (55).

Additionally, in the above-described configuration, the plate-shaped member (65) may support an exterior member (43).

Furthermore, in the above-described configuration, the main frame (16) may be formed in a tube shape by joining an outer frame member (66) positioned outside in the vehicle width direction and an inner frame member (67) that overlaps with the outer frame member (66) from inside in the vehicle width direction. The concave portion (64) may be a depressed part of the inner frame member (67).

Advantageous Effects of Invention

The saddle riding vehicle includes the body frame and the cable. The body frame includes the main frame extending rearward from the head pipe, the seat frame extending rearward from the main frame, and the rear frame extending rearward from the main frame and connected to the seat frame. The cable is routed so as to run along the body frame. The concave portion depressed in the vehicle width direction is disposed in the connecting portion. The connecting portion connects the main frame with the front end portion of the rear frame. The plate-shaped member that covers the concave portion is disposed. The cable is routed between the concave portion and the plate-shaped member.

With this configuration, since the cable is routed between the concave portion depressed in the vehicle width direction of the connecting portion and the plate-shaped member, the cable can be routed compactly. Additionally, even when the concave portion is disposed, since an influence to rigidity of the body frame is comparatively small, the concave portion is easily disposed in the connecting portion that connects the main frame with the front end portion of the rear frame. Furthermore, since the concave portion can be reinforced with the plate-shaped member, the rigidity of the body frame can be ensured.

Additionally, in the above-described configuration, the concave portion may be disposed in the side surface inside in the vehicle width direction.

With this configuration, the concave portion and the cable are difficult to be seen from the outside in the vehicle width direction, and therefore an appearance property is good.

Additionally, in the above-described configuration, the concave portion may open to the upper side and the lower side.

With this configuration, the cable can be routed in an up-down direction in the concave portion.

Furthermore, in the above-described configuration, the side kickstand detecting unit configured to detect the side kickstand may be disposed below the concave portion. The cable may be the cable connected to the side kickstand detecting unit. The endless driving force transmitting member that extends below the concave portion rearward from the main frame side and is connected to the rear wheel may be disposed. A clamp member that supports the cable may be disposed in the region surrounded by the driving force transmitting member as viewed in the side view of the vehicle.

With this configuration, the clamp member allows reducing a contact of the cable connected to the side kickstand detecting unit with the driving force transmitting member.

Additionally, in the above-described configuration, the plate-shaped member may include the step portion that bulges in the direction opposite from the depth direction of the concave portion. The cable may be routed between the step portion and the concave portion.

With this configuration, an interval between the concave portion and the plate-shaped member can be largely ensured with the step portion, the cable can be properly routed, and rigidity of the plate-shaped member can be increased.

Additionally, in the above-described configuration, the connecting portion may have the substantially triangular shape tapered toward the rear side from the main frame side as viewed in the side view of the vehicle. The concave portion may be disposed in the front portion of the connecting portion.

With this configuration, a rigidity balance of the body frame in the connecting portion can be satisfactory and an area to dispose the concave portion can be largely ensured in the connecting portion.

Additionally, in the above-described configuration, the plate-shaped member may support the exterior member.

With this configuration, the exterior member can be supported with the simple structure using the plate-shaped member.

Furthermore, in the above-described configuration, the main frame may be formed in the tube shape by joining the outer frame member positioned outside in the vehicle width direction and the inner frame member that overlaps with the outer frame member from the inside in the vehicle width direction. The concave portion may be the depressed part of the inner frame member.

With this configuration, by joining the outer frame member and the inner frame member together, the main frame can be easily formed in the tube shape, and the concave portion can be easily formed in the inner frame member. Additionally, the concave portion is difficult to be seen from the outside in the vehicle width direction, and therefore the appearance property is good.

With this configuration, the lower side clamp members 62, 63 allow reducing a contact of the cable 53 connected to the side kickstand detecting unit 52 with the driving force transmitting member 39.

Additionally, the plate-shaped member 65 includes the step portion 73 that bulges in the direction opposite from the depth direction of the concave portion 64. The cable 53 is routed between the step portion 73 and the concave portion 64.

With this configuration, the interval between the concave portion 64 and the plate-shaped member 65 can be largely ensured with the step portion 73, the cable 53 can be properly routed, and the rigidity of the plate-shaped member 65 can be increased with the step portion 73.

Further, the connecting portion 55 has the substantially triangular shape tapered toward the rear side from the main frame 16 side as viewed in the side view of the vehicle. The concave portion 64 is disposed in the front portion 55c of the connecting portion 55.

With this configuration, a rigidity balance of the body frame 10 in the connecting portion 55 can be satisfactory by configuring such that the rigidity of the connecting portion 55 decreases toward the rear side and an area to dispose the concave portion 64 can be largely ensured in the connecting portion 55.

Additionally, the plate-shaped member 65 supports the rear side cover 43 as the exterior member.

With this configuration, the rear side cover 43 can be supported with the simple structure using the plate-shaped member 65.

Furthermore, the main frame 16 is formed in the tube shape by joining the outer frame member 66 positioned outside in the vehicle width direction and the inner frame member 67 that overlaps with the outer frame member 66 from the inside in the vehicle width direction. The concave portion 64 is the depressed part of the inner frame member 67.

With this configuration, by joining the outer frame member 66 and the inner frame member 67 together, the main frame 16 can be easily formed in the tube shape, and the concave portion 64 can be easily formed in the inner frame member 67. Additionally, the concave portion 64 is difficult to be seen from the outside in the vehicle width direction, and therefore the appearance property is good.

Note that the above-described embodiments are given to illustrate an aspect to which the present invention is applied, and the present invention is not limited to the above-described embodiment.

While it has been described that the concave portion 64 is disposed in the side surface 55a inside in the vehicle width direction of the connecting portion 55 in the embodiment, the present invention is not limited to this configuration. The concave portion may be disposed in the side surface outside in the vehicle width direction of the connecting portion 55, and this concave portion may be covered with the plate-shaped member.

While the description has been given with the example of the cable 53 connected to the side kickstand detecting unit 52 as the cable in the embodiment, the present invention is not limited to this configuration. The cable only needs to have a long linear shape. Examples of the cable include an electric wire connected to an electric component different from the side kickstand detecting unit 52, a wire used for an operation or the like, and a pipe, such as a hose.

While the description has been given with the example of the rear side cover 43 as the exterior member in the embodiment, the present invention is not limited to this configuration. The exterior member only needs to be a member exposed to the outside of the vehicle body and may be, for example, a cowl that covers the vehicle body and a guard member that protects the vehicle body or the like.

Further, while the description has been given with the motorcycle 1 as the example in the embodiment, the present invention is not limited to this configuration. The present invention is also applicable to a three-wheeled vehicle including two front wheels or rear wheels or a saddle riding vehicle including four or more wheels.
